I just bought my diablosport tuner and am very happy with it so far!!! only bought it yesterday!! Went driving last night and out of the gate I still find her slow!!I have the 3" exshuast and the airaid cold air intake and throttle body spacer!! Im running 87 octane program now, but as soon as the tank is empty Ill run premuim!! Hoping this will change!! I cant find a CMR dealer here and was hoping to get other programs and settings to try!! I have no guts to play around with the shift points.Can somebody help me or steer me in the right direction Thanx
